DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment

With reference to FIG. 1, an electronic mail system includes a CPU 1, aROM 2, a RAM 3, a storage unit 4, a format converter 5, a scanner 6, anoperation panel 7, a data compressor 8, and a LAN (local area network)controller 9 which are electrically connected via a bus line.

The CPU 1 operates in accordance with a program stored in the ROM 2. TheCPU 1 provides a work area in the RAM 3, and accesses and uses the workarea during signal processing. The storage unit 4 includes, for example,a hard disk device which is used in storing data includingcompression-resultant image data of a facsimile format. The formatconverter 5 changes compression-resultant image data of the facsimileformat into corresponding image data of the e-mail (electronic mail)format. The scanner 6 converts an image of, for example, a documentsheet surface into corresponding binary image data (correspondingbi-level image data). The operation panel 7 has a key board, a startbutton, and other buttons. Information of the destination or the addressof an e-mail to be transmitted can be inputted into the electronic mailsystem by operating the key board on the operation panel 7. The scanner6 can be activated by operating the start button on the operation panel7. The data compressor 8 serves to compress binary image data (bi-levelimage data) which is generated by the scanner 6. The LAN controller 9includes a LAN interface.

The LAN controller 9 is connected via a LAN to an e-mail computer 9A.The e-mail computer 9A is connected to an e-mail network such as theInternet.

As previously described, the CPU 1 operates in accordance with a programstored in the ROM 2. FIG. 2 is a flowchart of a segment of the program.In the case where the transmission of information on a document sheet isrequired, the sheet is placed in the scanner 6 and information of adesired destination is inputted via the operation panel 7. Further, thestart button on the operation panel 7 is depressed.

With reference to FIG. 2, a first step S1 in the program segment decideswhether or not information of the destination or the address of ane-mail to be transmitted has been inputted via the operation panel 7. Inaddition, the step S1 decides whether or not the start button on theoperation panel 7 has been depressed. In the case where information ofthe destination of an e-mail to be transmitted has been inputted and thestart button on the operation panel 7 has been depressed, the programadvances from the step S1 to a step S2. Otherwise, the program repeatsthe step S1. Thus, the step S1 waits the reception of an e-maildestination and the depression of the start button.

The step S2 activates the scanner 6 so that an image of the surface of adocument sheet in the scanner 6 is converted by the scanner 6 intocorresponding binary image data (corresponding bi-level image data). Astep S3 following the step S2 transfers the binary image data from thescanner 6 to the data compressor 8. Then, the step S3 activates the datacompressor 8 so that the binary image data is compressed by the device 8into compression-resultant image data of a given facsimile format.Further, the step S3 transfers the compression-resultant image data ofthe facsimile format from the data compressor 8 to the storage unit 4before storing the compression-resultant image data of the facsimileformat into the storage unit 4. In the case where the transmission ofinformation on a plurality of document sheets (that is, a plurality ofpages) is required, the document sheets are sequentially scanned by thedevice 6 and the compression-resultant image data of the facsimileformat is stored into the storage unit 4 as a single file having aplurality of pages.

A step S4 following the step S3 transfers the compression-resultantimage data of the facsimile format from the storage unit 4 to the formatconverter 5. The step S4 activates the format converter 5 so that thecompression-resultant image data of the facsimile format is converted bythe device 5 into corresponding image data of the e-mail format. Inaddition, the step S4 transfers the image data of the e-mail format fromthe format converter 5 to the storage unit 4 before storing the imagedata of the e-mail format into the storage unit 4.

A step S5 subsequent to the step S4 transfers the image data of thee-mail format from the storage unit 4 to the LAN controller 9. The stepS5 activates the LAN controller 9 so that the image data of the e-mailformat is further transferred from the LAN controller 9 to the e-mailcomputer 9A. The image data of the e-mail format, that is, an e-mail, istransmitted from the e-mail computer 9A to the destination via thee-mail network 9B. After the step S5, the current execution cycle of theprogram segment ends.

The image data generated by the scanner 6 is of the binary type or thebi-level type. The compression-resultant image data of the facsimileformat which is generated by the data compressor 8 is also of the binarytype or the bi-level type. The format converter 5 successively encodespieces of the compression-resultant facsimile image data intocorresponding 7-bit character code words respectively. The 7-bitcharacter code words compose text-encoded image data. Thus, the formatconverter 5 changes the compression-resultant facsimile image data intothe corresponding text-encoded image data. The format converter 5 adds aheader of a given format to the text-encoded image data, therebycompleting the image data of the e-mail format. The header includesinformation of the destination, information of a source address,information of the data format, and information of the manner ofconversion from the image data into the character code words. The formatrelated to the header and the manner of conversion from the image datainto the character code words are in conformity with the Internet e-mainstandards referred to as MIME (Multipurpose Internet Mail Extensions).

Second Embodiment

FIG. 3 shows a second embodiment of this invention which is similar tothe embodiment of FIGS. 1 and 2 except for an additional arrangementdescribed hereinafter.

With reference to FIG. 3, an electronic mail system includes a CPU 1, aROM 2, a RAM 3, a storage unit 4, a format converter 5, a scanner 6, anoperation panel 7, a data compressor/expander 8A, a LAN (local areanetwork) controller 9, an inverse format converter 10, and a printer 11which are electrically connected via a bus line. The inverse formatconverter 10 changes image data of the e-mail format into correspondingimage data of a given facsimile format. The data compressor/expander 8Areplaces the data compressor 8 in FIG. 1. The data compressor/expanderSA serves to compress binary image data (bi-level image data) generatedby the scanner 6. In addition, the data compressor/expander 8A serves toexpand image data of the facsimile format into expansion-resultantbinary image data (expansion-resultant bi-level image data). The printer11 serves to print out expansion-resultant binary image data.

The CPU 1 operates in accordance with a program stored in the ROM 2.FIG. 4 is a flowchart of a segment of the program. With reference toFIG. 4, a first step S11 in the program segment decides whether or notdata of the e-mail format has been received by the LAN controller 9. Inthe case where data of the e-mail format has been received, the step S11transfers the received data of the e-mail format to the storage unit 4.The step S11 controls the storage unit 4 so that the received data ofthe e-mail format is stored into the storage unit 4. In the case wheredata of the e-mail format has not yet been received, the program repeatsthe step S11. Thus, the step S11 waits the reception of data of thee-mail format.

A step S12A following the step S11 decides whether or not the receiveddata of the e-mail format agrees with image data of the e-mail format byreferring to related information in the header of the received data ofthe e-mail format. When the received data agrees with image data, theprogram advances from the step S12A to a step S12B. When the receiveddata differs from image data, the program advances from the step S12A toa step S12C. The step S12B transfers the received data of the e-mailformat from the storage unit 4 to the inverse format converter 10. Thestep S12B activates the inverse format converter 10 so that the receiveddata of the e-mail format is converted by the device 10 intocorresponding image data of a given facsimile format. The step 12Ccontrols the LAN controller 9 so that a responsive e-mail representingan error will be transmitted to the source concerning the received dataof the e-mail format. After the step S12C, the current execution cycleof the program segment ends.

A step S13 following the step S12B transfers the image data of thefacsimile format from the inverse format converter 10 to the datacompressor/expander 8A. The step S13 activates the datacompressor/expander 8A so that the image data of the facsimile format isexpanded by the device 8A into expansion-resultant binary image data(expansion-resultant bi-level image data). Further, the step S13transfers the expansion-resultant binary image data from the datacompressor/expander 8A to the storage unit 4 before storing theexpansion-resultant binary image data into the storage unit 4.

A step S14 subsequent to the step S13 transfers the expansion-resultantbinary image data from the storage unit 4 to the printer 11. The stepS14 activates the printer 11 so that the expansion-resultant binaryimage data is visualized or printed out by the device 11. After the stepS14, the current execution cycle of the program segment ends.

As previously described, the inverse format converter 10 changes thereceived data of the e-mail format into the corresponding image data ofthe facsimile format. Specifically, the inverse format converter 10extracts text-encoded image data from the received data of the e-mailformat. Then, the inverse format converter 10 changes the text-encodedimage data into corresponding binary (bi-level) image data of thefacsimile format.

Third Embodiment

Thefont memory 12 includes, for example, a ROM which stores font dataproviding the relation between character code data and image data.

The CPU 1 operates in accordance with a program stored in the ROM 2.FIG. 6 is a flowchart of a segment of the program. With reference toFIG. 6, a first step S21 in the program segment decides whether or notdata of the e-mail format has been received by the LAN controller 9.This decision is to wait the reception of data of the e-mail format. Inthe case where data of the e-mail format has been received, the step S21decides whether or not the received data of the e-mail format agreeswith character code data by referring to the data format information inthe header of the received data of the e-mail format. According to theMIME standards, the data format information follows the information“content-type”, and denotes “text/plain” in the case where the relateddata of the e-mail format agrees with character code data. It should benoted that the data format information denotes “image/tiff” in the casewhere the related data of the e-mail format agrees with image data. Whenthe received data of the e-mail format agrees with character code data,the program advances from the step S21 to a step S22B. When the receiveddata of the e-mail format agrees with image data, the received data ofthe e-mail format will be processed as in the embodiment of FIGS. 3 and4.

The step S22B activates the font memory 12 so that the character codedata is converted into corresponding image data according to the fontdata in the font memory 12.

Information on a document sheet which is to be transmitted containsinformation of the destination or the address of a transmitted e-mail.Specifically, characters in a predetermined zone of the document sheetindicate an e-mail destination. Thus, the characters in thepredetermined zone of the document sheet correspond to the informationof the e-mail destination.

The CPU 1 operates in accordance with a program stored in the ROM 2.FIG. 8 is a flowchart of a segment of the program. With reference toFIG. 8, a first step S31 in the program segment decides whether or not astart button on the operation panel 7 has been depressed. In the casewhere the start button on the operation panel 7 has been depressed, theprogram advances from the step S31 to a step S32. Otherwise, the programrepeats the step S31. Thus, the step S31 waits the depression of thestart button.

The step S32 activates the scanner 6 so that an image of the surface ofa document sheet in the scanner 6 is converted by the scanner 6 intocorresponding binary image data (corresponding bi-level image data).

A step S33 following the step S32 extracts a portion of the binary imagedata which corresponds to the predetermined zone. The step S33 transfersthe extracted portion of the image data to the character recognitionunit 13. Further, the step S33 activates the character recognition unit13 so that characters represented by the extracted portion of the imagedata are recognized by the device 13. The character recognition unit 13generates information of a destination in accordance with the result ofthe character recognition.

A step S34 subsequent to the step S33 transfers the binary image datafrom the scanner 6 to the data compressor/expander 8A. Then, the stepS34 activates the data compressor/expander 8A so that the binary imagedata is compressed by the device 8A into compression-resultant imagedata of a given facsimile format. Further, the step S34 transfers thecompression-resultant image data of the facsimile format from the datacompressor/expander 8A to the storage unit 4 before storing thecompression-resultant image data of the facsimile format into thestorage unit 4.

With reference toFIG. 25, a first step S91 in the program segment decides whether or notthe mode selection button on the operation panel 7F has been operated.In the case where the mode selection button on the operation panel 7Fhas been operated, the program advances from the step S91 to a step S92.Otherwise, the program repeats the step S91. Thus, the step S91 waitsoperation of the mode selection button.

The step S92 decides which of the e-mail mode and the facsimile mode hasbeen selected by referring to a signal coming from the mode selectionbutton on the operation panel 7F. When the facsimile mode has beenselected, the program advances from the step S92 to a step S93. When thee-mail mode has been selected, the program advances from the step S92 toa step S96.

The step S93 decides whether or not information of a destinationtelephone number has been inputted via the operation panel 7F. Also, thestep S93 decides whether or not the start button on the operation panel7F has been depressed. In the case where the information of thedestination telephone number has been inputted and the start button onthe operation panel 7F has been depressed, the program advances from thestep S93 to a step S94.
